坐了這麼多年的飛機，我已經有點不清楚到底去過哪些機場了。以後恐怕越來越享受不到航空旅遊的樂趣了。 After so many
years of flying, I am no longer sure exactly which airports I have
been to. I’m afraid the joys of air travel will be scarcer in the
future.

要是能把去過的火車站也畫成地圖就太好了，不過想必很難。 It would be great if I could also
draw a map of all the train stations I have been to. It’s pretty
difficult though.
